The healing of a cut finger. Is it a physical or chemical change? Explain.

I would say it’s more chemical than it is physical. when you cut yourself there’s usually blood, correct? because a blood clot forms here & cells begin to work on the wound, which would be physical. the chemical part though is there’s an enzyme I think called thrombin which helps the formation of fibrin mesh. this helps stable the blood clot while the cells heal & close the wound with a potential small scar.
